“We anticipate many more urban
areas adopting bid-specification programs in the future. You have all the
existing nonattainment areas plus the
eight-hour ozone standard currently
under revision, which also will be driving the need to clean up older engines.

“When you think about it, there aremillions of older machines that aren’tTier 4 interim or Tier 4 final. There’sjust not enough revenue to replace allof them, so you’re going to have toretrofit for a number of years.”There are 15 machine models in-volved in what Deere says is the firstphase of what will eventually be a widerprogram. Kits are available throughJohn Deere equipment dealers.

The Deere equipment models
involved in this initial phase include
the 210LJ landscape loader, seven
models of J Series backhoes, the
710G backhoe, five four-wheel-drive
loaders — the 524K, 544J, 544K,
624H and 624J models — as well as
the 670C motor grader.

“The big deal about this announcement is that it’s one of the first times
a dealer can buy a kit that’s pre-engineered for a machine and essentially bolt the DPF system right on,”
Chrusciel said.

He added that the kits include theDPF and control system, hardware,as well as instructions on how to fitthe DPF under the hood. “There’snot going to be any re-engineering ofthe machine to make the DPF fit,” hesaid. “Nett has done the work to makesure they’ve positioned it under thehood such that it’s not going to causeproblems with the machine. They’vetaken into account the line-of-sightand other safety issues, so it’s prettymuch everything a regulator wouldwant to see in a retrofit program.”The program began last June withDeere Construction & Forestry deal-ers. However, John Deere PowerSystems engine distributors canalso develop under-the-hood kits forequipment manufacturers they sell to,Chrusciel said. dp
